| Abstract: | This paper introduces the piezoelectricity quartz thrust and thrust vector sensor in detail. The mathematical model of the sensor force system is established. The finite-element analysis to evaluate the natural frequency is used. By using the mode-testing method, a more precise test of the sensor was done in order to get the natural frequency,damping ratio and residual. By the experiment of static loading force, the static performance parameters of the sensor can be got. The experiment results testified that the thrust and thrust vector sensor possesses favorable characteristics, the linearity, reiteration and natural frequency all can fully reached the standard dynamometer stipulated.by CIRP-STCC. |
